signor to Kalif Corporation, Emeryville, Calif., a corporation of Delaware Application July 21, 1930. Serial No. 469,485 e claims. (C1. 113-99) Y This. invention pertains t a bearing bushing able holes formed in the adaptor plate. This press, and more particularly to a machine for plate 13 is provided with a pair of vertically ex pressing `a pre-,formed bearing liner into intitending guide posts 15 and a similar, but small.- rnate contact with the two halves of a split bearer, pair of posts 16, the purpose of which will ing to which it is to be soldered, or pressed, in be disclosed in the following description. 33j

As these parts are subadaptor plateV 13 is maintained in position upon merged in a molten bath, this bushing must Y this cradle by means of a pair of pins 14 exbe handled with tongs, and in order to facilitate tending upwardly from the cradle throughsuitits proper alignment with the bearing cap, itV 1101i is held against the guide posts 16, which serve to direct it into its proper position in the cap.

The connecting rod shank, which is illustrated at 31, is next put into place. Like the bearing cap, the bolt holes of the connecting rod shank are tted over the posts 15. Its wrist pin bearing is positioned over the pin 20 on the sleeve 19. The lever` 21 is then moved from the position shown in Fig. 1 to that shown in Fig. 2, causing the sleeve 19 and the pin 20, upon which the wrist pin bearing is now supported, to move downwardly, with the result that the upper half of the connecting rod bearing, or that half which is carried by the shank 31, is pressed into intimate Contact with the upper half of the bushing 30 while being guided by the post 15. The pressure thus exerted may be regulated by the position of the nutv 24 on the upright 17 and should be suilicient to form a very tight joint, not only between the upper half of the connecting rod bearing and the bushing 30, but also between the bushing 30 and the lower half of the bearing, or cap 29. Thus the bearing may be subjected to a predetermined pressure and the pressure maintained for any desired length of'time through the means of the locking feature of the lever.

The adaptor 13, carrying the pins 15 and 16, is so termed because it may be replaced by members of suitable dimensions to accommodate any size of type of bearing. Adjustment of the nut 24 upon the upright 17 will provide for accommodation of connecting rod Shanks of various lengths.

Another feature of the invention which is of great importance, is that the upright may be removed from the bath while the bearingis still held in its compressed position. It will be seen that the bearing cap 29, while theV pressure is being exerted upon it, is supported by the foot member 13 which, as has been stated, is integrally formed with the upright 17 and removable from the plate 13. When it is desired to remove the bearing from the bath the upright is lifted vertically so that the bolt holes of the bearing members slide free of the posts 15. The lower portion of the upright which then supports the bearing in its compressed position may be immersed in a cooling bath of lesser temperature or treated in any other suitable manner. l

While I have shown a preferred form of my invention, it should be understood thatvarious changes may be resorted to in theconstruction and arrangement of its several parts without departing from the spirit and scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:-

A machine of the character described comprising, a member for supporting a pair of bearing halves beneath the surface of a molten metal, means for guiding a bushing to an aligned position between said bearing halves, and press means for forcing said bearing halves into intimate contact with said bushing, said press means being adapted to be removed With said bushing and bearing halves from said supporting member and from said molten metal.

3. A device of the character described comprising a plate having a pair of vertically eX- tending` posts capable of being inserted through the bolt holes of a pair of bearing halves to hold the same in an aligned position, other posts carried by Vsaid plate for guiding a bushing into place between said bearing halves, and means cooperating therewith to force said bearing halves into intimate Contact with saidr bushing.

4. A device of the character described comprising a plate, means carried by said plate for supporting a pair of bearing halves and a bushing in alignment, an upright member having a horizontal extension on its lower end adapted to rest on s id plate and support said bearing halves, and'press means carried by said upright member and cooperating with said horizontal extension to exert a pressure upon said bearing halves and bushing.

5.
